The five-sided, five-level, multi-story building that headquarters the U.S. Military. It's the Pentagon in Virginia, just outside Washington DC.
I could have spent more time on this, but it was about a three-hour job on 123D Design. It was just for fun. Took about six hours to print at the second-highest quality setting our printer has.
I'll probably go back and re-work this project. There are some gaps between the inner and outer layers that are not uniform, along with some of the entryways (a couple are a little off center).
The next time I will start from scratch and design in a completely different way. But it was a fun learning experience.
